IMPROVEMENT IN LAND-ROLLER.

The Schedule referred to in these Letters Patent and making part of thename.

To Iall whom it mor/y concern Be it known that I, E. O. JONES, ofBrandon, in the county of Oakland, and State of Michigan, have inventednew and useful Improvements in Land-Rollers; and I do hereby declarethat the following is a full and exact description of the same,reference being had to the accompanying drawings, and to the letters ofreference marked thereon.

This invention consists in certain improvements in a form ofearth-rollen'for which Letters Patent of the United States were grantedme on the 21st day of April, 1868, said Letters Patent 'being numbered 77,048.

It relates more especially to aisectional roller, in which the middlesection is located between, and partially in rear ofthe two sidesections, and includes- First, a peculiar arrangement of the sections,by which the central section, in its revolution, cleans the inner edgesof the other two, thus preventing clogging.

Second, a peculiar construction of the flanged rim, which connects thestaves of the roller with the head,

- it being made in sections,lfor cheapness and convenpoised, over thebearings of the outer sections, for facility in turning.

Fourth, the construction and arrangement of the rear side of the centralpart of the main frame, by which the rear section is sustained whenelevated.

In the drawings, in all the ligures of which, the same letters refer toidentical partsl Figure 1 is a top view of my improved roller, with thedrivers scat and platform removed, showing the main frame,4 and thearrangement of the sections, the rollers, as, also, partof the markersand connections, and the projections in front of central roller.

Figure 2 shows an end view of the roller, part of the frame being brokenaway, to show the mode of suspension of the rear section, the driversseat and platform, and the markers in vertical position.

Figure 3 is an enlarged View of the sectional flanged supporting-rin g.

The outer sections of my improved roller are suspended in the frame A,which is composed of sidepieces a, front beam af, and central platforma2, of the width ofthe middle section, the whole being made of sufcientstrength to afford bearings for the sections of the roller, and tosustain the weight and draught. From the rear end of the side-pieces ofthe frame A rise two posts, sustaining a cross-beam, c, on which is' thedrivers seat, the whole being of suicient height to clear the rear, ormiddle section in itsntmost elevation. 'l

To these side-bars is also pivoted the frame which supports the rearsection. It consists of two vertical posts d d, pivoted, to permitvibration, a cross-beam,

E, and the' projecting arms ff, in the lower ends of which are thebearings of the central section,

The posts d d are pivoted, in this case, alittle in rear of the bearingsof the outer sections, and the anus ff are so constructed, being of bentform, Vas to hold the central section, when the posts d d are vertical,in rear of the bearings of the latter', so that,' when the posts d olare tipped forward by the depression of the platform, the centralsection of the roller shall be, lby `the Upon the rear part of thecentral platform a2 of the mainframe A are arranged projections Y Y, onwhich the central section rests when thrown forward. If desired, therear part of the frame may be extended backward for this purpose, farenough to receive the roller, the upper side being bevelled, orotherwise arranged, to permit the roller to pass easily upon it.

Any other suitable arrangement for the purpose may be made. It is onlynecessary that thefrear section shall be operated in such manner thatits weight may be borne by the bearings of the outward sections, and theswinging frame thus be relieved from all strain. during the operation ofturning.- ,i

There is also a standard, G, to furnish support for the platform.

' From the posts b b, also, vproject rearward, two arms h h, which carryon their ends a cross-bar, K.

To this cross-bar are attached the markers l E l, by means of smallrollers, which have their bearings `in short projecting arms from thebar K. j

Directly to the markers is attached, by cord or links, a rod,extending.r across the whole, and to the centre of this, by a rope1 orchain, a lever, which passes over the top of the frame, and isconvenient to the hand of the driver, and which may be 'held under acatch, if desired.' By depressing or elevating this 1ever, the markersare raised or lowered.

' These markers may be attached to the bar in other ways, withoutmaterial change.

The sections of my roller are of peculiar construction, shown moreparticularly in gs. 2 and 3.

vThey consist of a head, or disk in each end, to which are fixed angedrings. In these rings are two features. They consist of two flanges, atright angles with each other, one of which rests @ou the head, or disk,and is bolted thereto, and upon the other rest, and are bolted, the endsof the exterior planking, or staves.

As these flanged rings, if cast whole, are rendered useless by animperfection in any part, I have devised a sectional construction, asshown in the drawings, casting the ring usually in quarter-sections, forchcapness and convenience.

The central section, which has its axis of rotation far arrangement isto cause the forward part of the ends of the central section, which arein contact with the inner ends of the rear pai-tof the outward sections,to move downward, while that part of the outer, moves upward and thereverse, thus making the sections in contact constantly move in oppositedirections.

The rear section may be hung between the outer sections at any point inrear of the lines of the bearings of the latter, asthe same result willbe produced so long as the lines of their circumferences cut each other.

The thills, or shaft, are attached to the forward part of the frame, inany suitable manner.

The operation of this improved roller is as follows:

The described arrangement f the sections, while it permits the centralsection 'to be raised, in order that the roller may turn'more easily onthe outer, also e'ffects, by the contact of ends and the oppositemotions, that the sections keep ea'ch other from all clogging, andremoves a serious objection heretofore existing in sectional rollers.

The arrangement of the rear section upon the frame, and the location ofthe upper platform, permit the sec- It moves near to,

tion to be raised and thrown forward by the weight of the driver,stepping on the platform The section is thrown against th'e two pinsX Y,or other'similararrangement, and thus the weight of the whole is poisedover the axes of the forward sections, and the roller, easily turned,Without throwing undue weight on the,

, 3. The rear, or middle section of a sectional roller,

when attached, by means of connections, as described, pivoted to anypart of the main frame, substantially as described. y

This specification signed and witnessed, this 26th day of June, 1868.
